Heat (Mass) Transfer Distributions in a Rotating Two-Pass Channel with Angled Ribs Academic Article

abstract

• Experiments have been conducted to study the local heat (mass) transfer distributions in a two-pass test model of internal turbine blade cooling passages, with 60 ribs on the leading and trailing walls. For radial outward flow in the first pass, rotation did not significantly increase the local nor the overall heat (mass) transfer between consecutive ribs on the trailing wall. Rotation-induced Coriolis force lowered the relative overall heat (mass) transfer on the leading wall less in the rib-roughened channel than in a smooth channel. When the rotation number was high, there were twin peaks in the local heat (mass) transfer distribution between ribs on the leading wall. For radial inward flow in the second pass, the sharp turn reduced the difference between the heat (mass) transfer.on the leading wall and that on the trailing wall.
